Title: Dc-motor drive control device
Inventor: INOUE KIYOSHI
IPC: H02P7/288
Filed: 1978-10-24
Abstract: PURPOSE: To perform position control corresponding to the change in command signals in such a manner that its response is quick, correct, and stable by controlling positions and response speeds by the signal from an encoder which detects the movement of a dc motor.  
     CONSTITUTION: A logic circuit 8 gives the difference signal between the position- sensing signal which is output from an encoder 3 that senses the revolution of a dc motor 1 and a position command signal 14 to a differential control circuit 10 through a D-A converter 9. The output of the encoder 3 is also given to the differential control circuit 10 through an F-V converter 11. The differential control circuit 10 compares both input signals and gives the difference to the dc motor 1 through a V-F converter 12 and a driver 2.

Title: Etching liquid for compound semiconductor crystal
Inventor: UEDA TOMOSHI
IPC: H01L21/306
Filed: 1982-07-27
Abstract: PURPOSE:To detect the crystal defects of Hg, Cd and Te crystals and flaws on polishing and the like easily in a short time by mixing hydrochloric acid and nitric acid at the rate of 2:1-5:1 at a volume ratio to prepare a mixed liquid and mixing the mixed liquid and water at the rate of 1:1-1:5 at a volume ratio. CONSTITUTION:An Hg1-xCdxTe single crystal is cut by using a wire saw, etc., and polished by using abrasives such as alumina. The surface is specular-etched only by a fixed quantity by a Br methanol liquid. The polished Hg1-xCdxTe crystal is immersed in an etching liquid, and kept at the normal temperature for two or three min. The crystal is taken out of a vessel, washed by water, and observed by a metallurgical microscope of 500 magnifications. Accordingly, triangular pyramidal or square corroded holes (a pit) are formed rectilinearly along strain generated by flaws on polishing by a face orientation of a crystalline surface. When the crystal defect is generated, the corroded holes are generated in the crystalline surface at random and are not formed rectilinearly.

Title: Process controller
Inventor: ABE SHUJI
IPC: G05B13/02
Filed: 1985-06-18
Abstract: PURPOSE:To reduce the memory capacity by increasing successively the sampling cycle until a fixed number of pieces of sampling value stored in the memory are stable when the identifying signal is impressed to a controlled system and the output of the identifying signal is stored after sampling. CONSTITUTION:It is supposed that a memory has the capacity equivalent to only 10 samples. The stepped voltage is impressed to a controlled system as the identifying signal and the response to the voltage is measured. In this case, no response is obtained in an initial period L and then the response is gradually increased. Then the stable voltage is secured at a point B. The first ten samples are carried out at 0.5sec intervals and stored in a memory. However no stability is secured at this stage and therefore the sampling is carried out at 1sec intervals. In this case, the sample values obtained with 0.5sec intervals are thinned one by one and stored in the five front areas of the memory. While the sample values obtained at 1sec intervals are stored in the rear areas of the memory. The sampling cycle is increased until the stable result is obtained and the similar memory operations are carried out.

Abstract: PURPOSE: To enable a trainee to easily check the locus depicted by a face surface, etc., by providing the light receiving means of a target practice machine having light emitting means and light receiving means within a putter of golf, etc., or a target with a prescribed length. CONSTITUTION: The trainee installs the target 30, turns on a start switch 40 of the light receiving device 34 and sets the face 4 of the putter 1 toward the target mark 32 of the target 30. The trainee turns on a laser beam lighting switch 14 of the light emitting device 10 when the trainee thinks that the face surface 4 aligns to the target mark 32. A laser driving circuit 11 is then started and the visible laser beam is outputted from a sweet spot toward the target mark 32. The visible laser beam falls onto a phototransistor 35 and a buzzer 38 sounds when the face surface 4a faces the correct direction at this time. The trainee is, therefore, able to check whether the face 4 of the putter 1 is set at the correct plane of the target mark 32 or not.
